The radiator'in which the present invention has been embodied includesal c'oreunit xnadeup of a ynumber of vpreformed plates 19 suitablysecured together to afford av series of spaced lwater passagesforfthe'iiow ofl air therebetweemwith inlet and outlet headers or tanks'at opposite ends of the Water passages, and a hoop or and anchor orsupport the assembly in an ornamental shell or casing which -is mountedon the chassis frame of the vehicle.

It is one of the primary objectsof the present invention to provide animproved anchorf relation with each other, 25 arranged with respecttothe 4core that the age strap lorband for supporting the tank and corevassembly in the shell which will firmly hold the associated parts inproper core will be freed Vfrom x the imposition of thrusts or stressesincident to -frame Weaving, road shocks or the like.

@ther objects and features of advantage will become apparent during thecourse of the is mounted the radiator.`

following specification when taken in connectionvr with theaccompanying' drawings illustrating a preferred embodiment of theinvention. f

In the drawings:

Fig.x1 is a rear elevation of a radiator mounted upon av vehicle chassisframe and illustrating the application of the invention.

Fig. 2 is a fragmentary enlarged view of a portion of the structureshown in Fig. 1.

Fig. 3 is a detail view illustrating a slight modification. y

Referring specifically to the drawings,the reference numerals 1-1indicate a pair of longitudinally extending chassis frame members, and 2is atransverse member on which stance, the kcooling portion or core `3of the radiatoris shownas of the well known cellular type, preferablyconsistingl of a number band encircling the core" 15 and .tanks to holdthem'in assembled relation 'l portion of the core.

Thisparticular joint isdescribed .more/fully in my pending applicationfor'Patent Serial No'. 388,086. y l, 1^k Each of the straps 13 and le isprovided at suitable intervals withl rearwardly and outwardly extendingears 17 for attachment as vbvgmean's of studsj18 tothe rearward edge ofthe customary ornamental shell or casing gl. i

y19.V A fU-shaped supp'ortingstrap 2 1'se ycuredas bymeans of bolts'QQto the ,chassis frame member 2 hasits upwardl extending endportionsriveted orotherwlse fastened 'to' the sidewalls of the shellj19`wherebyl the shellis supported on the 'frame and turn Disconnection-of'the joint is'presupports, through the ears 17, of the anchor* age hoopor bands, the tank and core assembly. To steady and hold the assemblyfirmly in the shell or casing, a channel plate 24 may be secured to thebottom strap 127 and provided at opposite ends with slotted feet forengagement beneath the fastening studs 22.

In order that strains and side thrusts received by the anchorage straps13 will not be imposed upon the sides of the `core 3, it is proposed toprovide a lateral offset rportion 25 between the strap portions 12 and13 of slightly greater dimension than that portion of the coreoverhanging the side wall of the bottom tank 5, so that the lateraloffset portion 25 will contact with and abut the side wall of the tankand the adjacent portions of the side of the core and strap 13 will bespaced slightly from each other particularly at the connection or jointbetween the tank and core. Thus the likelihood of damage to the thin anddelicate metal of the core will be materiallyl reduced and any stresseswill be transmitted thru the lateral offset or foot directly to thestronger metal of the header or tank. l

In the event the bottom and side portions of the hoop are formed inseparate pieces as may sometimes be desirable, the invention may takethe form illustrated by vFig. 3. Here the end of the bottom strap 30 issecured as by soldering, welding or otherwise to the side strap 31 andthe lower end of the side strap is inclined outwardly vaway from theside of the core and provided with .a lateral or inturned foot 32 havinga dependent flange 33 for abutment with the side Wall of the bottomtank. As in the arrangement previously described, the core and par*ticularly the lower portion thereof secured to the tank will be freed ofthe damaging strains.

Various other forms of the invention will be apparent to those skilledin the art and there is no intention to limit the invention to the exactdetails referred to herein.

I claim:

1. In a radiator, a shell adapted to be mounted lon a support, aradiating unit encased within and directly supported through said shell,said unit including a bottom tank having an outturned marginal flange, aCore secured along its underside to said outturned flange with portionsthereof overhanging the side Walls of the tank, and an anchorage strapfor lmounting. the unit on the shell, having a portion thereof extendingadjacent the side of the core with a lateral .attachment projection andanother portion inset .adjacent thejoint between the core and outturnedflange of the tank for Contact with the side wall of the tank, saidinset portion being of slightly greater dimension than the, overhang ofthe core whereby to hold the side portion clear ofthe core so thatthrusts and strains are imposed directly on the tank through said insetportion rather than on the core and the joint between the core and tank.

2. In a radiator, a heat transfer unit, including a tank having anoutturned marginal flange, a core having one end joined to saidflangeand overhangino the side walls of the tank, and an anchorage bandcontractible about the core and tank to hold these parts assembled,portions of the band adjacent the joint between the core and outturnedflange being inset for a distance slightly exceeding the core overhangfor direct thrust engagement with the wall of the tank.

3. A contractible assembly and .anchorage hoop for encircling a heat4transfer unit of the type wherein the core is offset outwardly beyondthe side walls of an end tank, includ ing a strap adapted to extendclosely adjaA cent the side of the core, and provided with an insetportion corresponding to but of a dimension .slightly greater .than thecore olfset for direct thrust engagement vwith the tank wall.

' In testimony whereof I aliiX my signature.
